APPARATUS FOR REMOVING SURPLUS COATING METAL FROM WIRE.

SPECIFICATION forming part of Letters Patent No. 246,085, dated August23, 1881.

Application filed March 23,1881. (No model.)

To all whom it may concern Be it known that we, JOHN A. ORIOH, ofNaugatuck, in the county of New Haven and State of Connecticut, andFREDERICK Onion,

of Pittsburg, in the county of Allegheny and State of Pennsylvania, haveinvented a new and Improved Apparatus for Removing Surplus Coating Metalfrom Wire, of which the following is a specification.

IO In coating wire with tin or zinc the usual method for removing thesurplus tin or zinc from the wire as the latter leaves the bath is todraw said wirethrough a covering of sand, asbestus, or othernon-combustible substance that is placed on the surface of the bath butin this method tubes of scorite are quickly formed by the passage of thewire through the sand or asbestus, so that the latter ceases to wipe offthe surplus molten tin or zinc or does so imperfectly, and when inoperating upon a number of wires at a time the sand or other materialabout one wire becomes dirty or ineffective from scorite or from thesurplus metal that is wiped from said wire, all the wires have to bestopped to replace the dirty with clean sand.

The object of thisinvention is to provide a devicefreefrom theseobjections, that will rarely require the changing of the sand or otherwipa ing substance, and that is so arranged that the sand can be removedand replaced about one wire, when desired, without interfering with theother wires.

Figure 1 is a plan of the wire-cleaner, partly 5 in section. Fig. 2 is asectional side elevation of the same on line 00 :1), Fig. 1. Fig. 3 isan enlarged sectional side elevation of the same on line 3 3 Fig. 1,showing a modification of the adjusting device. Fig. 4 is a sectionalend elevation on line 2 2, Fig. 3. Fig. 5 is an end elevation, partly insection, on line 12 c, Fig. 2. Fig. 6 is a front elevation of a portionof one of the fixed supports of the tubes. Fig. 7 is an enlargedcross-sectional elevationof a sin- 4 5 gle tube.

Similar letters of reference indicate corresponding parts.

In the drawings, A represents a tank containing the molten metal forcoating the wires O, and B represents the sinker and its hearings incommon use for holding the said wires 0 beneath the surface of the metalbath A.

D is a bed for supporting the tubes H and their operating mechanism. Onthis bed D the bottom E of the tube-frame is secured by blocks and boltsa b, or other suitable device, and at the opposite ends of the bottom Eare the standards E, that complete the said frame. This bottom E iscurved rearward and upward to conform with the sweep ofthe swinging dooror valve F, that is pivoted on a rod, 0, which extends across from thetop of one standard E to the other. Said door or valve F is designed forthe purpose of holding the sand (represented at d) in the tubes H, andis forced and held against the larger and lower ends of said tubes H bymeans of eccentrics G, which are fixed on a rod, G, that isjournaled onthe standards E and is operated by hand-wheel G The lower edge of saiddoor or valve F is provided with series of parallel vertical slots f,through which the wires 0 pass into the tubes H. The sand or othernon-combustible wiping sub stance may be introduced into the tubes H ata point designated at g, Fig. 2, and the valve F be retracted, asindicated in dotted lines,

Fig. 2, for that purpose, and then forced by the eccentric G into theposition shown in full lines, thereby carrying and pushing said wipingsubstance into the tubes H.

Near the larger end oftubes H, and supporting the same, is a support, I,having semicircular edge depressions, h, in which said tubes H rest.Said support I is secured on the bed D by blocks and bolts t t. I

Near the smaller ends of the tubes H, and secured on the bed I) by boltsat either side thereof, are standards K, in which are fixed verticalscrews K, operated by hand-wheels K and on the screws K, and verticallymov able in the standards K, are blocks L, which support the oppositeends of a bar, L, that extends beneath the tubes H, so that by turn ingthe screws K the smaller ends of said tubes H may be elevated ordepressed at will.

A modification of this device is shown in Figs. 3 and 4, in which a pairof standards, M, are set, one on each side of each tube H in the bed D,and the tubes H are separately supported and secured between them bypins m,

passing through holes on in said standards M, so that said tubes H canseparately be adjusted at any desired elevation, as shown in Fig. 4. Asupporting-bar, m, is also secured to the standards m for asupplementary support to said tubes H. Ihe tubes H are constructed intwo longitudinal sections, H H the lower section, H, forming incross-section about three-quarters of a circle, and the upper section,Hi, forming about a quarter-segment. In a tube of this form the lowersection, H, will hold most of the sand or other wiping substance andprevent the escape of any when the section B is moved for renewing thesand, for taking up a broken wire, or for other purposes.

Oollars N are riveted or otherwise secured about the tubes H, the uppersection of a collar, N,'being hinged to the lower section thereof, asshown at n, and fastened, when closed, by hooks, clamps, or otherconvenient device, as indicated at 0. These collars N serve as hingesfor the partsof the tube H, and also to stiffen said tube, and bearingagainst the rear faces of the support I and supporting-bar L, preventthe said tubes H from moving in the direction of the pull of the wire 0.

0 represents a grooved rod or a series of rolls mounted in suitablestandards, 0, said 1011 0 being designed to guide, direct, and supportthe wires (1 as they pass from the tank A to the tubes H.

P represents a grooved roll or series of rolls mounted on suitablestandards. P, for guiding the wires 0 onto the drum Q, on which the saidires U are wound. As the wires 0 are drawn through the conical tubes Hsome portion of the sand is drawn forward into them, and because of theincreasing taper of said tubes H such sand becomes more and more firmlypacked toward the smaller ends of said tubes H, so that the pressure ofthe sand upon the wires 0 is gradually increased.

It will be seen that this arrangement (this device) will apply equallywell to one or any number of wires.

We are aware that wire from the zinc-bath is drawn through asbestus in achamber and there compressed by a plunger; also, that wire from thereels has passed round one series of rolls, over and underanotherseries, and thence coating metal from wire, the combination of tube H,tube-frame E E, and swinging valve F, arranged and operated as setforth.

3. In the construction of an apparatus for removing surplus coatingmetal from wire, a conical tube, H, made in two longitudinal sections,substantially as herein shown and de scribed, whereby the sand isretained in the tube when the upper tube-section is opened, as setforth.

4. In an apparatus for removing surplus coating metal from wire, thecombination, with the tube H, of the adjusting-screws K, blocks L, andbar L, supported in standards K, substantially as herein shown anddescribed.

5. In an apparatus for removing surplus coating metal from wires, thecombination, with the tube H, of the collars N, substantially as hereinshown and described, said collars serving to stiffen said tube, andserving.

also as hinges therefor, as set forth.

0. In an apparatus for removing surplus coating metal from wire, thecombiuatiomwith tube-frame E E, swinging valve F, and tube H, of theroll 0, substantially as herein shown and described, said rollbeingdesigned to guide, direct, and support the wire as it is drawnthrough said tube from the bath, as set forth.
